[junior ivy]

oh yeah I will play with 5k lines of code of internal unity class instead of injecting it as a property in my script and using it

[white yew]

If you have to do that, you're doing it wrong.

[floral estuary]

but the larger context you were using it in was that they thought it was ridiculous to have to do extra to do something so simple. The response that you could write code to write that code that should be default for you doesn't hold up imo

the base argument here is people shouldn't have to reinvent the wheel by creating functionality that should be default

[slender nymph]

so because they wanted it to already exist means my response of saying that it is easy enough to implement yourself is invalid? next time i'll just say "that is impossible because it isn't in unity already"

[slender nymph]

if you're so fussed about this feature not already existing in unity, then go suggest it on the roadmap. complaining that it doesn't already exist is not productive.

[signal mango]

Writing something that just spits out a function that does GetComponent calls is definitely on the lower end of difficulty

[floral estuary]

okay well ANYWAYS

https://github.com/OranBar/AutoAttribute-for-Unity3d I've used this in the past and it worked pretty well

[signal mango]

And most of the finicky annoying things to handle probably won't pop up in most code

You could use the undocumented __internalAwake callback to avoid needing to call it yourself or preventing the user from defining an Awake callback as well

[slender nymph]

no no no, you see, it doesn't exist in unity. and someone else already made it. so suggesting to someone that they possibly learn to do it theirself "doesn't hold up"

[white yew]

Can we stop the belittlement of correctness going on in here? If unity doesn't have the feature, suggest it on their roadmap.

Thank you.

How to deal with custom global settings in c# that need to be set before other classes can use it?
For example let's say that I have MyScript.cs and GlobalConfig.cs and I need Awake method of GlobalConfig called before MyScript because it needs properties of GlobalConfig.

[cosmic dagger]

Awake is used for setting internal references/data. Start is used for setting external references/data . . .

there is no way to determine the order Awake is called for a script . . .

[slender nymph]

technically you can set the script execution order, but if you're relying on that for your own code then you are gonna have a bad time

[cosmic dagger]

you can also set the script execution order, but it's not something you should rely on . . .

[junior ivy]

so how can I reference one script in another in a way that I can use it fully?

[keen owl]

I mean you could technically encapsulate the contents of the awake method inside an IEnumerator with a slight delay on top of the method but i’m not sure if that’s good practice in the long run

[junior ivy]

I've heard that I can set execution order of .cs scripts in project settings but that' a horrible idea, I want to use dependencies out of the box

in Godot I have a entry point script where I can set everything and prepare my scene by hand
in Unity... I don't have such control (probably)

[cosmic dagger]

huh? if you reference a script, you have access to all of its public members. it's always "fully"—if that's what you mean. there are many ways to get a reference: search by tag, use Find methods (not really recommended), or GetComponent . . .

oh, you can also make GlobalSettings a singleton if only one instance of it needs to exist . . .

[junior ivy]

I already have a GlobalConfig singleton

[keen owl]

Another idea would be to have two scripts on separate game object, with the one being called first on an active gameobject and the other on an inactive gameobject and set the inactive gameobject to active after a few milliseconds since your code won’t execute on inactive objects

[junior ivy]

but I can't depend on it because I have no guarantee that its properties are initialized

[keen owl]

Then make sure they are?

[cosmic dagger]

as i stated at the beginning. Awake runs before Start. just place the code for your other script in Start instead of Awake . . .

[junior ivy]

I don't use Start at all 😉 I want to access GlobalConfig in Awake

[cosmic dagger]

you should never use values (data) from anothe inside of Awake as it's mainly used to intialize internal values on the script itself . . .

Start is used to grab external references and use their data because it will be initialized by then . . .

[junior ivy]

but there are global settings common for all scripts and I need them in all Awake methods in all scripts

[cosmic dagger]

why not? that's the solution and normal. it's common practice . . .

it ensures initialization order . . .

[slender nymph]

why can you not just use Start for that?

[junior ivy]

I won't set myVar to 1 for every script I have... instead I want to have a GlobalConfig with myVar and control this property in one place

[cosmic dagger]

what is being set in GlobalSettings that you call in Awake?

[junior ivy]

potentially more than 100 different global options for my game that need to be set before any other script in awaken

[cosmic dagger]

to clarify, are you just assigning values to variables? can you post the script. this seems more of an architecture/setup issue . . .

[slender nymph]

again, why can you not just use Start to access that GlobalSettings object instead of Awake? why must this access happen in Awake

[junior ivy]

because I want to access global settings before the first frame happens

there are values that need to be initialized and Start is not for initialization afaik

[keen owl]

Then use OnEnable..

[slender nymph]

Start is for initialization. it just happens after Awake but before any Update runs

which is precisely why it is primarily used to access other objects

https://docs.unity3d.com/6000.0/Documentation/Manual/execution-order.html

[cosmic dagger]

this will work as well, but just like Start, it's called after Awake. apparently, they have issue with that . . .

[keen owl]

I believe OnEnable is called before Awake

[cosmic dagger]

nope . . .

[slender nymph]

OnEnable is called after Awake, but it is not guaranteed to be called after another object's Awake

[keen owl]

It’s the first thing that gets called when the script is activated in your scene, no?

[cosmic dagger]

Awake is the first . . .

• Awake
• OnEnable
• Reset
• Start

[keen owl]

Ah, I see thanks for letting me know

[junior ivy]

hmmm okay so I should use Awake ONLY for local config and then if I want to depend on some class I use it in Start so that I'm sure my dependency is initialized

[cosmic dagger]

Yes, but Awake is always called first . . .

[junior ivy]

that makes sense

[teal viper]

Boxfriend literally linked a page that explains it:
<#💻┃code-beginner message>

[cosmic dagger]

haha, boyfriend, i like that one . . .

[slender nymph]

yes, that is what you were instructed earlier #💻┃code-beginner message

[keen owl]

Yes, I didn’t look into the documentation you’re right

[teal viper]

Phone auto completion...

[cosmic dagger]

nah, it's cool. i'd have left it. adds flavor . . . 😏

[teal viper]

I'm not sure boxfriend would appreciate that lol

[slender nymph]

sometimes i forget that my username would normally autocorrect to that. i've been using it for more than a decade now so my phone has recognized it for a very long time. it is pretty funny to see it happen in the wild though

[cosmic dagger]

that was literally my first response to your question . . .

[keen owl]

Member on Steam since 2009, pretty legit lol

[cosmic dagger]

@junior ivy also, i was asking to see the script to check what type of values you're setting. if it's just assigning simple data, you can use an SO and reference that for any script that needs it . . .

[junior ivy]

I thought that I can't initialize things in Start because it's already a first frame

[cosmic dagger]

i'm not sure why; Start is called before the first frame update . . .

[junior ivy]

I've read it's called exactly in the first frame, not before

[internet]

[teal viper]

It does. But before the first frame is rendered.

There's no such thing as 0 frame

Awake is called in the first frame as well

[verbal dome]

It's even in the default template :p

[cosmic dagger]

0 frame does not exist. there has to be 1. it's just the start of it, so technically, before anything else . . .

[verbal dome]

I don't remember if Time.frameCount starts from 0 or 1 🤔 I think 0

[junior ivy]

if I imagine it in a low level, then it must be before the main loop so pretty much before the first frame

[teal viper]

Why? What is it in your game that would require that?
And while we're at that, Awake is called within the main loop.

[cosmic dagger]

either way, this doesn't affect you or what you're trying to do . . .

there are multiple ways to create an order of initialization that you can do. just pick one and test it . . .

[keen owl]

Both of them initialize but the Awake method is called even when the object is disabled so use Awake for critical initialization such as object references, etc, then use Start for scene specific initializations

[junior ivy]

weird because it means the main loop has to do at least one check on each iteration instead of initializing before the main loop

[teal viper]

Not sure what you mean by that. What check?

[teal viper]

You mean calling awake? Well, yes. How do you expect to initialize newly loaded gameObjects and scenes in the middle of the game(when the main loop is already running) then?

[junior ivy]

well I imagine that Awake is called for all scripts for all scenes that aren't even loaded

maybe bad assumption

[teal viper]

Indeed. How can it be called on something that doesn't even exist?

[cosmic dagger]

why? how can it call Awake in an unloaded scene (means it doesn't exist) on a GameObject that is not loaded (also doesn't exist) . . .

[junior ivy]

because I thought Awake it not related to scene loading or creation of base game objects

I thought awaking is a process called before all of that for all scripts in the project

[teal viper]

Nah. That would be crazy.

[keen owl]

Yes but you have to be in that scene. Imagine 300+ scenes running at once, you’ll crash lol

[naive pawn]

nothing is called on project scripts directly, they have to be added to gameobjects in scenes
when the scene exists, gameobjects exist, and then their components exist

awake is called on each component

[cosmic dagger]

Awake is part of a script's lifecycle. Scripts — MB classes — are attached to GameObjects, therefore, they are tied to the GameObject . . .

[junior ivy]

well not running but you would only initialize them, shouldn't be a problem in less than few thousands (depending on what is really going on under the hood ofc)

[naive pawn]

it would have quite a bit of overhead

there's a ton of scripts just in UnityEngine

also this doesn't make sense within the context of OOP, so maybe you should brush up on that

[cosmic dagger]

none of this affects what they originally wanted to do. that was already answered. at this point, they (seem) to be grasping at issues or looking for inadequacies . . .

[heavy knoll]

Anyone know why my unity project sometimes gets stuck on reloading domain forever and i have to close it in task manager? I've had this happen twice so far and it sucks

[cosmic dagger]

ouch, that's not cool. are you waiting for many changes, or just simple code fixes?

[heavy knoll]

just simple code fixes

i had it happen for the first time at the very start after i updated my project to unity 6

and then it just happened again a second ago

[cosmic dagger]

has to be unity 6 issues. i would check if other people experience the same thing. maybe the forums?

[heavy knoll]

ok

yea I've never experienced anything like that on any of my projects before this so that's probably the issue

Do you know if this is a good starting point so far for the survival resource node system i was trying to work on earlier, i decided to not do the scriptable object part just yet until i understand it a bit more, but this is what i have done so far https://paste.ofcode.org/LrDSfh8YRXypTWb7xfAc4d https://paste.ofcode.org/cBG644QjEDNFRqjYt9HVD9

I currently just have one monobehaviour script that is on both of my ore node types and is being accessed by the playerhit script on my player which when hit by a raycast triggers the DamageNode() Method which lowers the health by the damage amount

once the health is 0 on the ore

it triggers a new method called DropItems() and spawns in how many items are set to spawn in the inspector which are just prefabs of a cube with a rigid body for now dragged into the inspector as a reference

not really sure if this is good or not, any feedback would be appreciated

[teal viper]

Might be able to see where it's stuck by attaching the debugger to the process and breaking.

[teal viper]

It's a good start.

[heavy knoll]

How do I do that also is that something I have to do before it happens so if it happens again then I can see why?

[teal viper]

You'll need to learn how to use your ide debugger first. There are plenty of resources on that online.

Once you know how to work with it, just attach to the editor process and press the break all(pause) button. Then you can see the callstack of the current thread and switch between threads.

The details are too much to explain in discord. You'll need to learn it on your own. But feel free to ask if you have specific questions.

[heavy knoll]

Ok cool thx

[heavy knoll]

Do u have any tips/feedback on how to make it better/more modular

[teal viper]

Learn how to use scriptable objects. Other than that, you'll need to explain what exactly you want to be modular.

One advice I can give is:
Don't try to make a perfect system right away. You're developing this system for the sake of your project, not the other way around.
When you start working on a feature that the current implementation does not allow, think of how you can refactor/modify it such that this and other similar features would be implemented with ease.

Basically, this should be your workflow:
Feature required -> does the system allow for such a feature? -> if not, extend the implementation

Wrong approach:
??? -> how to make it more modular

[heavy knoll]

Ok thanks

[feral eagle]

quick and simple question
is it not posable to instantiate in a class variable. I might have asked this questions a couple of years ago I don't remember.

All one Example Code:

using UnityEngine;

//==== Main Class ====//
public class Example : MonoBehaviour
{
    [SerializeField]// Class Variable
    private ExampleClass exampleClass;

    [Serilised feld]
    private GameObject exampleObj;

    void Start()
    {
        if (exampleClass != null)
        {
            exampleClass.exampleObj = exampleObj;
            exampleClass.ExampleFunc();
        }
    }
}

//==== Variable Class ====//
[System.Serializable] // To allow customization in the Inspector
public class ExampleClass
{
    [SerializeField]
    private GameObject exampleObj;

    public void ExampleFunc()
    {
        Instantiate(exampleObj);
    }
}

[cosmic dagger]

Instantiate is a static method from UnityEngine.Object. you need to access it from the type . . .

[astral falcon]

How did you come to your conclusion? Did you get an error that might have said whats wrong?

[cosmic dagger]

also, it has nothing to do with calling it from a field (class variable), but from a C# class instead of a MonoBehaviour . . .

a C# class has no concept of Unity or where Instantiate came from . . .

[feral eagle]

Thank you @cosmic dagger You were right. It needed MonoBehaviour. I was worried that adding MonoBehaviour would not work or might break it, but that was exactly what it needed to work.

[teal viper]

ExampleClass class is not the same as Example class

[feral eagle]

I don't know why i thought that the ExampleClass variable would pull from Example classMonoBehaviour

[astral falcon]

And adding a monobehaviour should be treated as a component, so added not instantiated

[ionic zephyr]

In an RPG type game in order to show the different maps (cities,plains,castles) is it all done in the same scene but changing the tilemap or is it done in any other way?

[lilac turtle]

how do i change variables from one script in another?

on left click im casting a ray which can detect if it hit an enemy but when it hits i want it to change the enemy's health variable

[strong wren]

The RaycastHit you get has a reference to the other transform/collider. You can call GetComponent on those component references to get other components on the gameobject.

[strong wren]

Either way is fine. How people would end up leaning depends on a lot of details regarding overall project structure.

[lilac turtle]

but the game is designed to have hundreds of enemies

do i have to reference to them all..

is there a way to do it with tags?

[strong wren]

You don't have to hold on to the references, just temporarily use the ones the physics system is handing to you

[acoustic sequoia]

how do i assign both of these to the same property? doesnt make sence
tmpColorTitle.fontStyle = FontStyles.Normal FontStyles.UpperCase;

[slender nymph]

https://unity.huh.how/bitmasks#combining-masks look at the second example which uses an enum

[loud topaz]

maybe someone can help me: why are backfaces grey and not white? (no settings changed in the material). the faces turn as i click them.

[teal viper]

Because they're back faces. Probably having the normal facing down(since it's the back of the front face). You'll either need a custom shader that somehow accounts for that or just make a mesh with double faces.

If you don't care about lighting, use an unlit shader and there would be no difference.

[loud topaz]

i see. changing the direction of the normals should fix this issue, right?

[rough bough]

how can I detect if my player collides with something?

[burnt vapor]

https://docs.unity3d.com/Manual/CollidersOverview.html

[rough bough]

Thanks 🙂

[teal viper]

It would fix the back faces, but it would cause the same problem for front faces.

[real thunder]

does Start() within monobehavior of a GameObject I just spawned on a frame runs at the same frame?

[burnt vapor]

Start will be called in the first valid frame when the object becomes enabled. Which means the first frame on scene load and the same frame on object creation/instantiation.

cool, thanks

hi! i m with unity tests, for some reason i cant find a way to start it in my pacman, i think is because i cant instantiate it...

could i ask for some help? !code correctly please twt

yeah, unit test are awful xp

[burnt vapor]

What does "I can't find a way to start it in my pacman" mean?

heres the playtest, ghost and the createObject, which seems to me that it doesnt initialise

You are doing new Ghost() which is invalid

Ghost is a MonoBehaviour, you shouldn't use constructors with those

Nvm It's an array of Ghost[] 🤦‍♂️

[severe onyx]

Trying to think of an elegant way to execute code when the value of an enum changes, with different functions called depending on what the value was changed to. Right now my best idea is just putting a big ol' switch into the setter. Is there a better way to do this?

[burnt vapor]

https://learn.microsoft.com/en-us/dotnet/api/system.componentmodel.inotifypropertychanged?view=net-9.0

This is the proper way to notify of value changes

Related: https://learn.microsoft.com/en-us/dotnet/api/system.componentmodel.inotifypropertychanging?view=net-9.0

Alternatively, if the aim is just to notify of a single value or event, use the event pattern or UnityEvent

[west radish]

How should I decide whether to make a new class derive from MonoBehaviour or not?
For instance, my Garden tool has a component that defines the rectangle the garden exists inside.

There's no actual reason why that Rectangle component needs to derive from MonoBehaviour, but at the same time, theres no reason why it couldnt be a Mono class

[burnt vapor]

It derives from MonoBehaviour when it relies on hooking onto the Unity lifecycle

If it doesn't need that, you can go lower. For example, have it inherit from Behaviour or Component.

[west radish]

sure, but as my Garden already is part of the lifecycle, and my Garden is the actual main thing that runs everything, theres no real need for my gardens components themselves need to be in the lifecycle

I could give my Rectangle class its own Update function, then when Garden updates I can call Rectangle.Update myself

[burnt vapor]

Perhaps you should also consider if your classes must be part of Unity's base classes anyway. If you don't use Unity features such as instantiating or otherwise hooking onto gameobjects, maybe you can make a basic class.

[burnt vapor]

Generally I do advice that you have a smart parent component with dumb child components that just listen to the parent and send events to it. If you want a proper hierarchy the child should generally not do anything

[rapid mountain]

is an object data type good to use in general?

[runic lance]

article is a bit old, but should help you decide 🙂
https://unity.com/blog/engine-platform/10000-update-calls

[west radish]

speed/optimisation isnt a concern

[burnt vapor]

What is an object data type? Please give more context

Json related?

[runic lance]

the biggest differences are probably in performance and usage pattern
if everything inherits from MB (or similar) you're always going to have inherited fields that are possibly unused
for MBs you need to Instantiate and then setup the object somehow, with POCOs you have the constructor

[frail wind]

guy can anyone tell me the diffrent betwen
"GetComponent<Rigidbody>().linearVelocity = Vector3.up * jumpHight;"
and
"myRigidbody.velocity = Vector2.up * jumpHight"
i know it make player jump but what the diffrent?

[runic lance]

I personally enjoy decoupling everything I can from MBs

[rapid mountain]

like a object someVariable; as oppose to any generic data types in c# or unity. I've seen it on some codes and from what I can tell the object data type can represent anything

[runic lance]

additionally MBs are bound to hierarchy lifetimes, POCOs not necessarily

[burnt vapor]

It can. If you are able to use generic types then you should prioritize using it over objects due to boxing (). Also, you can use a base class for more specific types where you might use polymorphism and use different inherited classes

Generally you don't need object. If a method can return multiple values you should probably use a generic type with a generic constraint. If you have a variable that can represent multiple values, you should look into base classes

And if neither are applicable, object is also completely fine, but you should definitely do some pattern matching to determine the correct type.

[west radish]

its the layout of my Garden tool thats the issue.
Garden will be my MonoBehaviour and for all intents and purposes, Garden is the actual GameObject.
Then the Components are all used by the Garden to produce the final result.

As Garden is definitely a MB, that sort of removes the need for its components to also be MB

[rapid mountain]

ohh okay okay, so use it sparingly as possible thanks for the clarification!

[cosmic dagger]

the first example gets the Rigidbody component to access linearVelocity

the second example uses a Rigidbody variable to access linearVelocity

the difference is the first example calls GetComponent, and the second example uses a component reference. the second version is preferred as it avoids calling GetComponent every time you need to access the Rigidbody component . . .

[frail wind]

i also have other question. what is vector2 and vector3?

[cosmic dagger]

object is not preferred as it will (most likely) involve boxing to convert the data to the intended type . . .

[frail wind]

i just type it and dont understand what it mean

[cosmic dagger]

these are very simple. you can actually look up using the unity !docs. they have information on all of their API classes with a definition and example . . .

[eternal falcon]

Documentation

💻 API

📖 Manual

[frail wind]

thank

[rapid mountain]

yeah that's what I noticed as well, I really wouldn't go through the hassle of converting it to the correct data type either

[burnt vapor]

It's not a bad thing, but you have the boxing which is defenitely something to avoid

But unless you introduce variables that get a lot of boxing (like each frame), you probably should not worry about it

[cosmic dagger]

i'd question why you need to use object in the first place. the data type itself should suffice or T for generics . . .

[rapid mountain]

I just saw it while looking up on something, it's actually the first time I ever encounter of the data type

[burnt vapor]

Yeah so it definitely depends

Even better, if this is with Json for example you might even want to consider using JObject

This can be anything, doesn't need a base class, but also prevents boxing I believe?

[cosmic dagger]

it's always good to know what exists. i mean, it is the base type of all C# objects . . .

[burnt vapor]

I think it still boxes, but it is more flexible over object

[runic lance]

boxing happens when you treat a value type as a reference type, like casting Vector3 to object

using a JObject to wrap a Vector3 will still create a reference type containing the value type, so no victory there

if you're only dealing with reference type there wont be boxing anyway

[burnt vapor]

Regardless you'd allocate the JObject anyway, so even if there was no boxing it made no difference

Still, a thinn to think of in terms of flexibility

[stuck palm]

if a parent is disabled, will that call ondisable on the children too?

[cosmic dagger]

time to open up unity . . .

[swift crag]

If a behaviour's game object is not active in the hierarchy, then it will have OnDisable sent to it

(even if enabled is still true)

https://docs.unity3d.com/6000.0/Documentation/ScriptReference/Behaviour-isActiveAndEnabled.html

[stuck palm]

I see, thanks

[swift crag]

annoyingly, this behavior of behaviours is not described clearly in the documentation

it's implied by the OnDisable example

https://docs.unity3d.com/6000.0/Documentation/ScriptReference/MonoBehaviour.OnDisable.html

// These functions will be called when the attached GameObject
// is toggled.

And you bungled it up!

[hexed terrace]

google -> unity input.getkey -> read docs

[wintry quarry]

Have you tried looking at example code to see the right way?

That's not what I said

Have you tried looking at example code?

Example code?

[wintry quarry]

Yes

[obsidian dagger]

Like from unity learn?

[wintry quarry]

any example of anyone using GetKey

from anywhere

[obsidian dagger]

Ah

Well im following a vid rn

ok so look at what they did

and look at what you did

they are completely different

Fix yours so it's like theirs

[obsidian dagger]

Oh wait

Im so dumb

When you are programming you can't just write something that is "sorta similar", it needs to be exact.

[obsidian dagger]

Im so sorry i didn't notice the key code

it's not just the KeyCode part

look at everything

Why is it telling me its expecting a ";" but when i put it there it underlines the entire code, and what exactly does the ; do (why do we close lines with it) so i understand it for future reference

[wintry quarry]

because else cannot have a condition

[obsidian dagger]

Ah huh

[wintry quarry]

maybe you meant to write else if?

Again, pay closer attention to your tutorial

[obsidian dagger]

Oh

[wintry quarry]

Exactly

[obsidian dagger]

No wonder i do terribly at school

I have the attention span of a rock

[swift crag]

consider working on it

[swift crag]

; is used to end a statement.

[obsidian dagger]

Doing my best

[swift crag]

Single-line statements are things like...

int x = 123;
Foo();
return 1;

you also have block statements:

{
  int x = 1;
  x += 1;
  x = 5;
}

An if statement runs the next statement only if the condition is true. You often use block statements so that you can do more than one thing!

[obsidian dagger]

gotchu thanks man

[swift crag]

if (foo)
  Foo();
else if (bar)
  Bar();
else
  Baz();

and

if (foo)
{
  Foo();
}
else if (bar)
{
  Bar();
}
else
{
  Baz();
}

are equivalent

Hi guys i am begginer in unity and c#. Does anyone know how camera for third person in unity should look like, i have my code for camera and movement but i can't make camera rotate how i would like, if anyone can help i would be thankfull

[tired hull]

i just installed visual studio code desktop but i cant find it in my package manager on unity?

[swift crag]

Unity's Cinemachine package can help you out here

Especially for a third person follow cam -- it has a "Third Person Follow" mode

[swift crag]

Your IDE is not visual studio code

you sent screenshots of Visual Studio

[wintry quarry]

Why did you do that

That's a different program

[obsidian dagger]

Im glad yall are supportive and patient it means alot to me

[trim moon]

i was watching brackeys video on that, and he made camera and player movement in one script, but can i make it in 2 separate scripts?

[swift crag]

I don't know what "visual studio code desktop" is

[wintry quarry]

Visual studio and visual studio code are totally different programs

[swift crag]

you can do whatever you want! but if you used Cinemachine, you wouldn't be writing code to move the camera

You'd just add a Cinemachine camera and tell it "please follow the player"

[trim moon]

oh ok i will try now

[swift crag]

along with some parameters for how it should position itself

https://docs.unity3d.com/Packages/com.unity.cinemachine@3.1/manual/get-started.html

Check this out

[trim moon]

so do i delete my camera code?

[swift crag]

If you've never used Cinemachine before, make sure you install the 3.0 version

I dunno which one is the default right now

[swift crag]

You can hang on to it if you want, but you probably won't need much

[tired hull]

oh ok sorry but it seems that my IDE (visual studio) is up to date

[trim moon]

ok thanks i will try it now and will tell you later if it works

there is third person aim camera, is that it?

[wintry quarry]

Ok, that's not what the instructions are about though. Read the instructions to set up Visual Studio to work with Unity.

[swift crag]

This is how I have my third person camera configured.

Ah, but yeah -- that's what you want!

That'll be pre-configured

You'll want to make it target either the player's root (the object that holds every other player object) or maybe the player's chest bone (if it's human-shaped)

notice how mine targets an object called "Third Person Root"

which is just an empty object parented to my player object

[trim moon]

it is just a cube

you are doing God's work man btw this have helped me a lot i just need camera to follow mouse do i do it in code?

[tired hull]

i cant seem to find the devenv.exe in my IDE directory?

[viral comet]

Can anybody help me? it says :

"'object' does not contain a definition for 'rotation' and no accessible extension method 'rotation' accepting a first argument of type 'object' could be found (are you missing a using directive or an assembly reference?)"

[ivory bobcat]

Is your Visual Studio correctly configured to work with Unity?

[swift crag]

Interesting -- this means the IDE things that transform is a System.Object

Can you share the entire script? !code

[swift crag]

this is short enough to just paste inline anyway

so yeah, there's your problem

You have declared a field named transform

its type is object, which is shorthand for System.Object

[ivory bobcat]

Remove private object transform;

[swift crag]

That's the top-level type in C#.

It's very very vague!

[tired hull]

in my IDE folder in visual studio

[trim moon]

sorry if i am bohring to you fen i have added a script to my main camera so it moves with my cursor and it did not work, than i have added debug log to see it in console, and console detects that i am moving my mouse but screen does not move

[ivory bobcat]

And make your PlayerCam inherit MonoBehaviour

[viral comet]

now it gives me this

[swift crag]

If you're using Cinemachine now, you'll need to do something to make the Cinemachine Camera look in a different direcetion

[swift crag]

the other problem is that this isn't even a MonoBehaviour

notice how your class does not inherit from anything

You've got methods named Start() and Update(), so it sounds like you meant to inherit from MonoBehaviour

[viral comet]

ITS FIXXED!

holy shit, yall are so smart

[swift crag]

As-is, it's just a "plain old object"

[trim moon]

i am using cinemachine and i have set everything how i like but it doesn't move when i move mouse, anyways it does move with my character so i did that good right?

[viral comet]

thank you so much

[swift crag]

no prob (:

You can now attach PlayerCam to a game object, since it's now a component

[swift crag]

Why do you expect the camera to rotate right now?

[tired hull]

is the devenv.exe supposed to be a conf file because thats the only one i can find

[trim moon]

cause i have added a code for it to move on main camera or should i add it to cinemachine camera?

[swift crag]

Cinemachine controls the main camera

You use Cinemachine Cameras to tell it how to do that

Have a look at the documentation I linked earlier

[ivory bobcat]

Show your preference window?

[swift crag]

It'll explain how Cinemachine works

[ivory bobcat]

It should look something like

[obsidian dagger]

How do you put a ≠ sign in c#? I dont have it on my keyboard and iirc there was a sign for it

[ivory bobcat]

Looks fine. If your ide isn't configured make sure you added the Unity workload when installing/modifying Visual Studio

If you run the Visual Studio installer again, it'll allow you to modify Visual Studio instead of installing.

[daring hare]

!= ?

[obsidian dagger]

Let me try that rq

[viral comet]

hey, it says my Input Axis X is not setup, do you have a solution?

[swift crag]

You probably want "Horizontal" and "Vertical"

[viral comet]

i just started coding last night, I only know the bare minimum

[viral comet]

yeah

[swift crag]

you're currently using the old Input Manager. You can see all of the axis definitions in the project settings

[ivory bobcat]

It would look like this. Where you'd want the Unity workload (top left) to be installed - the rest are optional/unnecessary.

[viral comet]

where would i find this?

[sonic plover]

project settings

[swift crag]

open the Project Settings window (it's in the "Edit" menu in the menubar for me)

not to be confused with Preferences, which is for personal settings

[tired hull]

ive just updated unity via the installer but i already have unity game dev enabled in modify

[viral comet]

found it, what now?

[ivory bobcat]

After it's configured, you ought to get some red squiggly lines here if everything's working correctly

[swift crag]

just have a look at the names -- those are the only valid inputs to GetAxis

[viral comet]

so i would replace "GetAxisRaw" with Mouse X and Mouse Y?

[ivory bobcat]

Start would also be capitalized and the Visual Studio should not identify it as a miscellaneous file.

[viral comet]

sorry, i honestly have no idea what im doing lmao

[ivory bobcat]

It's definitely not configured atm.

After you've added the Unity workload, you may need to reboot Unity.

[obsidian dagger]

How'd you guys learn coding?

Im just following a tutorial i know what this and that does but i have no idea how to write code on my own

[wintry quarry]

Went to school

[obsidian dagger]

Oh im just learning this as a hobby to help my depression and its actually working and i love it

Can you recommend me to somewhere where i can learn?

[wintry quarry]

To just learn C# on its own you could look at https://dotnet.microsoft.com/en-us/learn/csharp

I think it's a good idea to know C# decently before starting UNity (but it's not the only way to learn)

It will make it a lot easier though

[obsidian dagger]

Ah

gotcha

[obsidian dagger]

Do i learn this on pc or can i do it on my phone?

[wintry quarry]

PC is much better. You will be able to interactively learn

[obsidian dagger]

Alright

[wintry quarry]

on the phone you'd just be passively watching videos

which is less likely to "stick"

[obsidian dagger]

Yep true

[tired hull]

@ivory bobcat all the other errors are gone but im still getting this error

[viral comet]

    }
    
} 

Can somebody help me out? it says my input axis X is not setup?

urgent!

[wintry quarry]

Pretty clear error

You don't have an axis called "X"

I think you probably want "Mouse X", which is a predefined one?

You can see your input axes in Project Settings -> Input Manager.,

Also just FYI it is an error for you to be using Time.deltaTime here. it's going to make your looking around very jittery

[swift crag]

didn't I explain why "X" isn't a valid choice? :p

[viral comet]

i didint comprehend

[swift crag]

also, you still have private object transform; in there, and this still isn't a MonoBehaviour

[viral comet]

because im special

[wintry quarry]

So say that and ask for clarification

[viral comet]

I did

[sharp echo]

where i crate a class???

[wintry quarry]

[sharp echo]

thanks!

[swift crag]

you are currently trying to get a value for an input axis named "X". There is no such axis.

the Input Manager lists all valid axis names, such as "Horizontal" and "Vertical"

[trim moon]

i am allowed to add screen record?

[viral comet]

coding hurts my brain

[swift crag]

if you have absolutely no idea what you're doing then you should stop whatever it is you're doing and follow the beginner pathways on Learn

[trim moon]

this is the closest that i want my camera to act like, just can't figure out how to like fix it to not have this much move. Btw i did read what you send to me and i still can't understand what to do hahahaha

[swift crag]

I'm talking to Christmas here, not you

[trim moon]

i know i just wanted to tag you

[swift crag]

You need to turn down the damping values

Higher values mean the camera moves and rotates more slowly

[shadow rain]

does anyone hav any idea y this isnt working?

[wintry quarry]

Coroutines cannot delay other code

coroutines can only delay themselves

[swift crag]

otherwise the entire game would freeze

[wintry quarry]

You would have to put the next line inside the coroutine, and after the wait, if you want it to happen after the wait

[shadow rain]

ok

[viral comet]

what do i need to do to fix my problem. Do i need to switch "X Axis" with MouseX?

[trim moon]

thanks man it do look better now but it is still not what i would like it to be, i will try and figure it out on my own from now, sorry for bothering you

[swift crag]

I said the problem is that you're trying to use this as an axis name:

"X"

You need to use a valid axis name, such as:

"Horizontal"

I don't know how to explain it and more clearly than that

[viral comet]

ohhhhh

[wintry quarry]

As mentioned several times, you need to use an axis name that exists. "X" is not one. "Mouse X" is one,

[viral comet]

ohhh

shit

i comprehended it!

i got it now

[swift crag]

oh yes -- you want "Mouse X" here

"Horizontal" would be arrow keys

[spare mountain]

or the a and d in wasd, right?

[swift crag]

yeah, I think you get both

[quartz oyster]

I have this, works fine but for some reason on mobile its not smooth at all, I tried upping the animationDuration but it still wasnt smooth

private IEnumerator MovePanel(RectTransform panelRect, Vector3 startPos, Vector3 endPos)
{
float timeElapsed = 0f;

while (timeElapsed < animationDuration)
{
    panelRect.anchoredPosition = Vector3.Lerp(startPos, endPos, timeElapsed / animationDuration);
    timeElapsed += Time.deltaTime;
    yield return null;
}

panelRect.anchoredPosition = endPos;

}

[swift crag]

I only use the new input system, so I'm pretty fuzzy on theo ld input manaegr

[viral comet]

SO instead of X i would put Horizontal?

[spare mountain]

haven't done a deep dive into either tbh

[swift crag]

both are mapped

[swift crag]

If you want mouse input, use "Mouse X"

[wintry quarry]

How and here are you starting the coroutine?

[spare mountain]

I presume you mean where

[quartz oyster]

StartCoroutine(MovePanel(rectTransform, rectTransform.anchoredPosition, openPosition));

On a button click

[viral comet]

ahhhh

im smart

[flat sphinx]

why arent these enums

[swift crag]

unity would have to generate a source file based on your Input Manager settings

these aren't "hard-coded" into the engine

[quartz oyster]

@wintry quarry

[swift crag]

note that things like "the Q key" are enums -- see KeyCode

[viral comet]

SO IN THEORY, this should work?

using System.Collections.Generic;
using UnityEngine;

public class PlayerCam: MonoBehaviour
{
    public float sensX;
    public float sensY;

    public Transform orientation;

    float MouseXRotation;
    float yRotation;

    private void Start()
    {
        Cursor.lockState = CursorLockMode.Locked;
        Cursor.visible = false;
    }
    private void Update()
    {
        //get mouse input
        float MouseX = Input.GetAxisRaw("X") * Time.deltaTime * sensX;
        float mouseY = Input.GetAxisRaw("Y") * Time.deltaTime * sensY;

        yRotation += MouseX;

        MouseXRotation -= mouseY;
        MouseXRotation = Mathf.Clamp(MouseXRotation, -90f, 90f);

        // rotate cam and orientation
        transform.rotation = Quaternion.Euler(MouseXRotation, yRotation, 0);
        orientation.rotation = Quaternion.Euler(0, yRotation, 0);
    }
    
}

a

wrong msg reply

oh well

[swift crag]

You are still using the wrong axis name here

It doesn't matter what you name those variables

[viral comet]

fudge

[swift crag]

You really need to stop and use !learn

it doesn't seem like you understand very much about C# at all -- which is fine, you're new

but you need to have a better handle on what's going on here

[viral comet]

you're right

[quartz oyster]

I have this, works fine but for some reason on mobile its not smooth at all, I tried upping the animationDuration but it still wasnt smooth, i call it like this : StartCoroutine(MovePanel(rectTransform, rectTransform.anchoredPosition, openPosition));

{
float timeElapsed = 0f;

while (timeElapsed < animationDuration)

[toxic cloak]

does anyone knows how to kill a specific tween if i set an id transform.DOScale(new Vector3(1.2f, 0.8f, 1.0f), moveDuration / 2).SetLoops(2, LoopType.Yoyo).SetId("StretchSqueeze");

[rich adder]

DOTween.Kill("StretchSqueeze");

god I hate this doc you can't link specific sections

https://dotween.demigiant.com/documentation.php

[toxic cloak]

thanks just found it

[languid spire]

I dont use it but does Dotween not return anything from the methods like StartCoroutine for example?

[rich adder]

iirc it returns a Tween

[languid spire]

so that should be stoppable, no?

[rich adder]

yeah you can stop the Tween that way too

been a bit since I touched Dotween, been using another solution lately 😛
https://github.com/KyryloKuzyk/PrimeTween

[dark laurel]

@toxic cloak What's much easier (and less likely to .. be problematic if you have multiple items with the same tween string/int) is to just save a tween or sequence as a private member, and check if it's running when you need to kill/complete it

I have a pattern I use almost everywhere.. lemme dig it up and clean it up for ya

[rich adder]

yeah much better to store the Tween

strings are dirty

[dark laurel]

(and also just break if you have 2 components with the same id)

[languid spire]

Seems a much more logical way to do it

Tween tween = transform.DOScale(...);
...
tween.Kill();

updated

[swift crag]

Yes. Keep a reference -- much like with coroutines.

[dark laurel]

not necessarily - that just pauses it

[rich adder]

i think its still Kill

tween.Kill()

[dark laurel]

sometimes you want to kill it (when the object is deleted) and sometimes you wanna complete it (because you have something important to do OnComplete)

sec i'm trying to find my original doc.. i literally just have a printout nearby because I use this pattern that often and always forget it 😛

private Sequence _revealTween;
private void OnDisable() => StopTweens();

private void StopTweens()
{
    if (_revealTween?.IsActive() == true) _revealTween.Kill(); // or .Complete()
}

something like that

[rich adder]

the primetween docs is also so much better

[dark laurel]

rhys mentioned to me last year that he was gonna do a different tweening library - is that his?

nope, i'm not familiar with this guys

[rich adder]

not sure who that is lol

[dark laurel]

I'll have to check it out

[rich adder]

yeah its pretty good, someone else here suggested last time.

[dark laurel]

He's been less active in this discord since his product is nearly market ready, but it's rhys_vdw (not gonna ping him). Guys a genius.

[toxic cloak]

Thanks

[dark laurel]

I'm a bit too vested in the DOTween infrastructure.. i have a zillion (personal) utilities and libraries for it, so it's a bit much for me to change.. but I really would love to chat with 2020-Sharping to make a different decision

Like - why is there not a better "gravity" tween (instead of the weird-ish bounce tweens).. Or why isn't there any support for randomness in tweens.. or tween pooling.. etc

Or like, why do I need to either specify an ID or save a reference to kill/complete a tween instead of just letting the tween/sequence know when I create it what I want it to do when the GO dies/pauses/etc

[languid spire]

lol, if in doubt roll your own

[dark laurel]

I'm too old to roll my own.. just barely smart enough to know that I'm not smart enough to do it

[languid spire]

too old? to me?

[dark laurel]

I mean, I do appreciate that DG.DT has a pretty robust api surface, and for all intents and purposes it works, but i hate the docs

haha

"too old" at heart.

I've written one thing that I've OSS'd and I'm proud of, and it's so tiny and niche that I can't imagine applying the same effort to a full tweening library.. i'm happy to slap my own shitty extensions on someone else's work and gripe about it unfairly :p

[languid spire]

man, youve had 4 years at least to write a tweening library, it takes literally weeks

[dark laurel]

You're right, I had nothing else to do in those 4 years :p

[swift crag]

Of course, you could also write a wrapper for it

[languid spire]

I gotta admit, the first time I needed a tweening library I looked at what was available and thought, wtf they are crap, so wrote my own

[dark laurel]

Here's a better example - sometimes I have what I call a "hit text" in my games - like numbers that float up in the UI from a position in the game.. but if the object underneath dies/disappears I want the hittext to continue to animate.. but if the LEVEL or something else ends, I want it to just delete instantly. Looks like this:

    public class HitText : BetterMonoBehaviour
    {
        private Sequence _seq;
        private bool _isTweenCompleteNormally = false;

        public void ShowAndDestroy(string text, float duration, Color startColor, Color endColor)
        {
            Vector2 newPos = new(transform.localPosition.x + NumberUtils.Next(MinX, MaxX), transform.localPosition.y + NumberUtils.Next(MinY, MaxY)); // random end position, based on some min/max constraints
            _seq = DOTween.Sequence();
            _seq.Insert(0, transform.DOLocalMove(newPos, duration));
            _seq.Insert(0, Text.DOColor(endColor, duration));
            ... more to it, but you get the idea ...
            _seq.AppendCallback(() => _isTweenCompleteNormally = true);
            _seq.OnComplete(() => Destroy(gameObject));
            _seq.Play();
        }

        private void OnDisable()
        {
            if (!_isTweenCompleteNormally)
            {
                _seq?.Kill();
                _isTweenCompleteNormally = false; // Set this to false so destroy doesn't try to destroy the GO again.
                Destroy(gameObject);
            }
        }
    }

this approach tracks the tween status directly with a bool (which gets "completed" at the end of the tween), and when the GO is disabled, if it's not complete, it just kills it

(normally "on complete" destroys it)

[languid spire]

should this not be true?
_isTweenCompleteNormally = false; // Set this to false so destroy doesn't try to destroy the GO again.
other wise the enclosing if is still true

[dark laurel]

hm - been a while since I actually looked at this closely, but I think if I didn't have that flag then destroying it in OnDisable led to problems if the GO was destroyed elsehow

(that object was already destroyed or marked for destruction)

like Destroy() doesn't actually destroy it, but instead calls OnDisable and then Destroy

I seem to recall that I had a pretty hard lock without the flag

in this case, we want the hit text just destroyed/stopped if the parent GO is disabled but not destroyed, actually, despite what I said above

hey, I have a problem with this spray and the problem is that when I hit a wall, the car flies through the walls using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class CarController : MonoBehaviour {

public float MoveSpeed = 50;
public float MaxSpeed = 15;
public float Drag = 0.98f;
public float SteerAngle = 20;
public float Traction = 1;

    private Vector3 MoveForce;


void FixedUpdate() {

    
    MoveForce += transform.forward * MoveSpeed * Input.GetAxis("Vertical") * Time.deltaTime;
    transform.position += MoveForce * Time.deltaTime;

    
    float steerInput = Input.GetAxis("Horizontal");
    transform.Rotate(Vector3.up * steerInput * MoveForce.magnitude * SteerAngle * Time.deltaTime);

    
    MoveForce *= Drag;
    MoveForce = Vector3.ClampMagnitude(MoveForce, MaxSpeed);

    
    Debug.DrawRay(transform.position, MoveForce.normalized * 3);
    Debug.DrawRay(transform.position, transform.forward * 3, Color.blue);
    MoveForce = Vector3.Lerp(MoveForce.normalized, transform.forward, Traction * Time.deltaTime) * MoveForce.magnitude;
}

}

[frosty hound]

Your issue is that you're moving with transform.position which teleport its to the next position rather than using physics.

You need to use a rigidbody and take the MoveForce and apply it as actual force to the rigidbody.

thx

but I have a stupid problem that I'm just starting with programming in C# and I don't really know how to do it

[steep rose]

I know Microsoft has a C# course for you to learn C# solely https://dotnet.microsoft.com/en-us/learn/csharp

If you want to learn unitys API with C# you can do so via the pathways https://learn.unity.com/pathways

[tulip stag]

hey! just a general beginner question— why is VS more recommended than VScode for unity?
Anything wrong with using VScode? Or should I stick with VS? I always used VS without questioning why just because I was told it's the right one for unity but after stepping away from unity dev and trying out other projects I'm left wondering what's so different about the two

[wintry quarry]

It has better Unity integration

More consistent and less fragile

P.s. a lot of people use Rider too

[green flame]

Hello! Did I miss something in my code ? I would like my "mobs" follow the character. But my code do really nothing x)

        GameObject playerObj = GameObject.Find("Character");
        for (var i = 0; i < mobs.Count; i++) {
            float step = mobs[i].speed * Time.deltaTime;
            mobs[i].UnityGameObject.transform.position = Vector2.MoveTowards(mobs[i].UnityGameObject.transform.position, playerObj.transform.position, step);
        }

[tulip stag]

oooo I never heard of this one

[rich adder]

Put logs

[polar acorn]

What function is this in

[rocky canyon]

Rider is pretty solid.. it wasn't until recently that there was a free version you'd have to rely on early access versions... (also rider is pretty good at showing u optimizations in real-time)
the other ones can do this as well w/ AI plug-ins now-a-days

VSCode is my go-to IDE, for one I use certain plug-ins to code for embedded microprocessors.. And its lighter, and faster, and easier for me to jump around projects..

VSStudio is more of a full fledged IDE.. that VSCode can't directly replicate w/o the use of plugins. but nothing that can't be remedied

[green flame]

In the Update() ^^

[tulip stag]

So, as a beginner to both Unity and programming in general— VSStudio?

[rocky canyon]

💯 thats where I started

[polar acorn]

1. Don't use Find in update. Find the character once, and keep using that reference.
2. Try logging step and mobs[i] to see if they're the values you expect (you might be referencing prefabs, or have accidentally set speed to 0)
3. check if the mobs objects have a component that conflicts with teleportation like CharacterControllers

[rocky canyon]

you'll have the easiest transition into coding and unity w/ imo

as u progress then you'll have the know-how and ur own preferences on where to go from ther

[green flame]

First point done, ty!

First 3 logs from here

[polar acorn]

Where do you set mobs? Are they objects in the scene, or prefabs?

[green flame]

mobs is a simple List that I use to store objects from my own class called "Mob"

In the UnityGameObject I store the associated GameObject and in speed a simple float

[frigid sapphire]

I have this issue where all my prices aren't updating, value changes but text remains the same, can anyone help? https://paste.ofcode.org/a5q3yp5Nz8CsetNhy6vDJ2

[green flame]

set at 4.0f

should I maybe add a certain component to my prefab used to spawn mobs ?

atm my class is really empty no conflict possible I think ^^

List<Mob> mobs; // -> In the top of the class

And somewhere when I want to create the mobs I have:

GameObject scePrefab = Resources.Load<GameObject>("alien1_prefab");
Instantiate(scePrefab, new Vector2(prefabX,prefabY), Quaternion.identity);
mobs.Add( new Mob("name", scePrefab));

My mob spawn properly ^^

[cosmic dagger]

You shouldn't need Resources to spawn a prefab. Assign the prefab to a variable and use that variable in Instantiate . . .

[green flame]

Then I should in the Start function instantiate a reference to the prefab instead of use it each time ?

[cosmic dagger]

What script spawns the mobs? That script should have a reference to the mob prefab . . .

[green flame]

I created a script called "GameManager" which is used like an emulator to spawn enemies etc..

[cosmic dagger]

Also, this code passes the prefab to the Mob class, not the instantiated clone. You need to assign Instantiate to a variable and pass that variable instead . . .

[cosmic dagger]

That's fine, but I would use a script solely for managing and spawning the mob (MobManager) as a game manager encompasses managing game state and world values . . .

[green flame]

My current goal is not to do something perfect but just something working to learn a little bit Unity then yes I'm not focused on optimisation ^^

But thank you for your advices, I have changed some lines to optimize the thing (declaration on top..)

btw, my mobs is currently not moving x)

Logs are OK for me, the move code too I think ?

[cosmic dagger]

That's not an optimization. Typically, a script describes what it does and only pertains to one behaviour, hence, "mono" behaviour. I was trying to help steer you away from creating a monolithic GameManager class with everything inside of it . . .

[green flame]

Then is it better to create ScriptableObject?

[cosmic dagger]

They're not moving because you pass in a reference to the prefab (the object used to spawn into the scene) instead of the instantiated GameObject . . .

[rocky canyon]

^ this is a fundamental type tid-bit

very important to learn

[cosmic dagger]

From my earlier response, you need to store the instantiated GameObject into a variable and pass that variable. Then you'll have the correct reference to the GameObject from the scene

Checkout Instantiate from the unity !docs. They have an example of this . . .

[tawny edge]

I finished the project 4 in Unity programming course!

[rich adder]

are you going to make a small game based on what you learned?

thats the best way to put into practice and drill in the info

[tawny edge]

i'm always between that or continuing the course 😭

[rich adder]

tbh just running through the course it might no "stick" as much you using what you learned so far for another mini-project

like trying to replicate from scratch what you did without following the page

[tawny edge]

funny thing is, doing a personal mini project IS part of this course 😅 which is why i'm always in doubt.

[rich adder]

oh yeah then keep at it 💪

[tawny edge]

after each section, the course instructs to work on your own personal thing based on the design document you made..
It's where i struggle the most

[rich adder]

yea cause thats where ideally you're not just copying info down, you're trying to force your brain to recount and rebuild that from memory / knowledge learned

I have horrid short term memory, its not so much a quick memorizing thing, maybe more of a "muscle" memory I think.

[tawny edge]

i feel you, my memory and attention spam are short, so i resorted to using Trello to note my thoughts and decide what the next course of action should be.

[cosmic dagger]

Very true; after watching a tutorial or learning smth from a blog, it's best to immediately redo the very thing you learned without looking at the resources

You will see how much you've retained and what you need to work on . . .

[quartz oyster]

I have this, works fine but for some reason on mobile its not smooth at all, I tried upping the animationDuration but it still wasnt smooth, i call it like this : StartCoroutine(MovePanel(rectTransform, rectTransform.anchoredPosition, openPosition));
on a button click

private IEnumerator MovePanel(RectTransform panelRect, Vector3 startPos, Vector3 endPos)
{
float timeElapsed = 0f;

while (timeElapsed < animationDuration)
{
    panelRect.anchoredPosition = Vector3.Lerp(startPos, endPos, timeElapsed / animationDuration);
    timeElapsed += Time.deltaTime;
    yield return null;
}

panelRect.anchoredPosition = endPos;

}

[rich adder]

in what way is not smooth? maybe cause you're seeing your FPS capped

code itself looks fine

[quartz oyster]

Could be, its like I can see it move bit by bit almost and doesnt give that smooth sliding in effect

[rich adder]

go back to testing on your Editor. Put Application.targetFrameRate = 30 see if it looks the same

from the manual

• Android and iOS: Content is rendered at fixed 30 fps to conserve battery power, independent of the native refresh rate of the display.

[lunar hollow]

How can i change the Texture of a Specific Face and get the Texture of a Specific Face of a MeshRenderer?

[rich adder]

easier said than done. Iirc you need proper UV split and all that

[lunar hollow]

Oh wow

[rich adder]

does it have to be a specific face ? and why runtime

[lunar hollow]

Im trying to make a Source based Lightning System (In source only the faces texture go either darker or brighter)

[rich adder]

You want to make your own lighting system ?

this is more of a #archived-code-general or #archived-code-advanced and beyond my monkee brain comprehension

[lunar hollow]

Oh okay

[swift crag]

I don't understand what that means

[tiny hearth]

Not sure where to put this, but I've been getting this error everytime I try to compile:
UnityEditor.dll assembly is referenced by user code, but this is not allowed. UnityEditor.BuildPlayerWindow:BuildPlayerAndRun ()

It is only when I include a library folder of plugins:

None of these plugins (to my knowledge) have any unity editor reference.

ClientCommon, AsyncData, GameServerCommon, are all my libraries with no unity references anywhere.

Is there anyway I can cause unity to give a stack trace on the build error, or more information than just "but this is not allowed"?

[verbal dome]

Hmm see if the !logs have any more info

Thank you. didn't know of the logs. I've discovered the problem.

[verbal dome]

What was it?

[tiny hearth]

I have client and server code in the same unity project; the client code has the "ClientCommon", and so does the server. These are seperate library folders. I seem to have forgotten to provide the necessary dependencies to the Client lib folder to handle it's library.

The struggle was not having a stack trace.

Thank you so much.

[verbal dome]

Np👍 Logs often have the info that is missing from errors

Was it related to newtonsoft here?

[tiny hearth]

Yes, it requires that dependency.

[acoustic sequoia]

Hey everyone, quick question. I have a Task running during an event in my game. when the user presses pause, the games timescale is set to 0. everything is the game pauses except on a very very rare occasion this method seems to run infinitly fast..

the method im about to share is supposed to spawn enemies every (x) amount of time.. but when i pause, the enemies will eradically spawn (RARE).

public async Task StartSpawning(RallyPoint activeRally)
  {
    if (activeRally.spawnsPerMin == 0)
    {
      Debug.LogError($"spawnsPerMin is set to 0 : {activeRally}");
      return;
    }
    currentRally = activeRally;
    isRallyActive = true;
    float elapsedTime = 0f;
    float spawnInterval = 0f;
    float rallyDuration = activeRally.totalRallyDuration;
    float spawnrRateMultiplierActivated = 1f;
    float rate = 60f / activeRally.spawnsPerMin;
    float critialMomentSpawnIntesity = 1 - (currentRally.critialMomentSpawnIntesity / 2f);
    float criticalPoint = rallyDuration * currentRally.critialMomentStartTime;

    while (isRallyActive)
    {
      elapsedTime += Time.deltaTime;
      elapsedTime = Mathf.Clamp(elapsedTime, 0f, rallyDuration);
      if (rallyDuration - elapsedTime <= criticalPoint) spawnrRateMultiplierActivated = critialMomentSpawnIntesity;

      rallyManager.rallyTimer.SetTimer(rallyDuration - elapsedTime);

      currentRally.TimerTextInitialize();
      if (elapsedTime >= rallyDuration)
      {
        currentRally.Completed();
        EndRally();
        return;
      }
      if (!isRallyActive)
      {
        return;
      }

      if (spawnInterval == 0f)
      {
        SpawnEnemyGroup();
      }

      spawnInterval += Time.deltaTime;
      spawnInterval = Mathf.Clamp(spawnInterval, 0f, rate * spawnrRateMultiplierActivated);

      if (spawnInterval >= rate * spawnrRateMultiplierActivated) spawnInterval = 0f;

      await Task.Yield();
    }
  }```

[obsidian plaza]

maybe try waiting to execute pause code at the end of the frame? could that have an impact

[cosmic dagger]

deltaTime is affected when your game is paused. try using unscaledDeltaTime instead . . .

[acoustic sequoia]

hmm ok interesting, i'll look into it.

[acoustic sequoia]

no i need the game to pause, that's not the issue

[cosmic dagger]

oh, so you don't want this to continue running?

[obsidian plaza]

it’s incorrectly pausing i think

[swift crag]

so you're saying that enemies will occasionally spawn way too fast?

[acoustic sequoia]

if you look closely at my post you'll notice that i DO want time to be affected by the pause. the issue is that it rarely does continue for no reason i can figure out

[swift crag]

are you sure that SpawnEnemyGroup isn't malfunctioning?

[acoustic sequoia]

exactly, but while the game is paused only

[swift crag]

you can throw some log statements in there to find out how many times your code is running

[acoustic sequoia]

so,, the issue is that it is so rare, i don't know how to debug it, i could be playtesting for hours just to get it to happen once...

[obsidian plaza]

would try this then because it sounds like something thats only happening sometimes when other parts of the code takes too long

[swift crag]

How do you know the issue lies in this code at all?

[acoustic sequoia]

i'm genuilnly curious, how could that function me malfunctioning? it's not effected by anything.. it has to do with the while loop im almost certain

[swift crag]

well, I can't see the code

it could be anything

it could be a method that says if (Time.deltaTime == 0) { SpawnThreeTrillionSpiders(); }

[acoustic sequoia]

  {
    int enemyIndex = GetRandomEnemyIndex();

    Vector3 pos = Vector3.zero;
    float randomAngle = Random.Range(0, 360);
    for (int i = 0; i < currentRally.amountPerSpawn; i++)
    {

      if (inactivePools[enemyIndex].Count == 0 || activePool.Count >= activeEnemyLimit) continue;
      Enemy enemy = inactivePools[enemyIndex][0];
      enemy.player = player;
      enemy.data = enemyTypesArray[enemyIndex];

      inactivePools[enemyIndex].Remove(enemy);

      if (activePool.Contains(enemy)) activePool.Remove(enemy);
      activePool.Add(enemy);

      enemy.transform.position = player.transform.position + Vector3.up;
      enemy.transform.RotateAround(player.transform.position, Vector3.forward, randomAngle);

      enemy.transform.Rotate(new Vector3(0f, 0f, -randomAngle));
      if (pos == Vector3.zero)
      {
        Vector3 direction = (enemy.transform.position - player.transform.position).normalized;
        pos = player.transform.position + direction * currentRally.spawnDistance;

      }

      Vector3 newPos = pos + Random.onUnitSphere;
      newPos.z = 0f;
      enemy.transform.position = newPos;
      particleManager.CreateSpawnEffect(newPos);
      if (i == 0)
      {
        soundManager.PlayClip(enemySpawn, newPos, 1);
      }



      enemy.gameObject.SetActive(true);
    }

    int GetRandomEnemyIndex()
    {
      int enemyIndex = Mathf.FloorToInt(Random.Range(0f, enemyTypesArray.Length));

      if (inactivePools[enemyIndex].Count != 0 || enemyTypesArray.Length == 1) return enemyIndex;
      else
      {
        for (int i = 0; i < 10; i++)

            enemyIndex = newIndex;
            return enemyIndex;
          }
        }
      }
      return enemyIndex;
    }
  }```

[acoustic sequoia]

hahahah

[swift crag]

that seems fine; there's no time dependency in there

I would add a bunch of logging so that when the issue does happen again, you'll have more information

[swift crag]

I don't actually know what happens when you await Task.Yield();. I've only done a little bit with async methods in a Unity context (and most of that has been involving Awaitable

[acoustic sequoia]

when i add alot of logs in while loop my comp slows down so much

[swift crag]

Do you get a very large number of spawns in one frame?

[verbal dome]

From my understanding it always waits for at least one frame, sometimes more.
Need to investigate further though..

[swift crag]

if you think it's pause-related, I'd suggest writing code to pause and unpause the game very rapidly. that might help to trigger the bug more often

[acoustic sequoia]

from what i know, im pretty sure await Task.Yield(); allows the while loop to perform on the next frame kinda

[swift crag]

is there a reason you aren't just using a coroutine?

I'm much more familiar with that behavior

[obsidian plaza]

i was about to say

[acoustic sequoia]

I thought about doing this as a last resort. see if you guys had a better idea than me

[verbal dome]

Most people use coroutines in this type of situations, yeah.

Only reason I really use async is for stuff that needs to run in the editor too (I know EditorCoroutines exists but what if I want them to also work in playmode)

[acoustic sequoia]

yes there is a very big reason why i'm not using coroutine. and the quick answer is becasue coroutines don't allow the 'flexibility' i need to run my opperations. i have alot of Tasks waiting for other ones to complete and a few other reasons.

[cosmic dagger]

i don't think Task is affected by the timeScale, or unity related Time. maybe that's why it acts up randomly and runs . . .

[obsidian plaza]

i mean at the end of the day why not just hard code in that the code doesnt execute at 0 timescale

[acoustic sequoia]

no it is. becasue every other task i have running will pause when the user pauses. this is the only task* with a bug

[swift crag]

I wouldn't expect it to have any bearing

[cosmic dagger]

yeah, i've never messed with Task before, so this is uncharted territory . . .

[swift crag]

that's why this is weird to me, yes

https://docs.unity3d.com/6000.0/Documentation/ScriptReference/Awaitable.html

you may be interested in this

[cosmic dagger]

Awaitable is their own version of using Task, right?

[swift crag]

It's an alternative, yes

[acoustic sequoia]

so here is what i'm thinking... I think when the game pauses specifically when the spawnenemygroup is suppoed to run, the while loop continues with the same elapsedtime -> resulting in running the same condition over and over again

[verbal dome]

You are correct in that Task.Yield isnt affected by time/time scale. It just waits until the next time it gets a chance to check

[swift crag]

I've used it for a game before. The game actions are implemented as Awaitable-returning methods. If I'm just simulating game logic, I skip all of the visual effects and the methods basically run synchronously. If I'm displaying an action, I run effects and await the completion of each step

[verbal dome]

Which is usually the next frame

[swift crag]

I have to wonder if it's not always the next frame 😉

All you're doing is throwing your task back into a queue

[acoustic sequoia]

ya, so should i have a check before spawning to check if the game is paused? (seems like a temporary fix)

[cosmic dagger]

place a check within the top of the loop for timeScale being 0 and yield; that should stop it from running . . .

[acoustic sequoia]

i guess i'll just do that just to see if i ever see the issue again...

[swift crag]

I'd suggest adding a check that you aren't spawning twice in the same frame

log a warning if it happens

that'll help you spot the issue if it manages to happen again

[acoustic sequoia]

idk what you mean can you write a line of code expressing what you mean?

[swift crag]

Using Task.Yield() lke that is very alien to me

[swift crag]

presumably just if (Time.timeScale == 0) { Task.Yield(); }

of course, if it's instantly resuming the task, then you'll spin forever (:

I don't know how it behaves

[cosmic dagger]

just check if timeScale is 0 (basically, when the game is paused). if so, yield . . .

[swift crag]

I would suggest using Awaitable, which lets you explicitly wait for the next frame

[acoustic sequoia]

but waiting for the next from doesnt make any sense becasue when the game pauses, the frames continue... so that wouldn't fix it?

[swift crag]

so what?

the timescale is zero

[cosmic dagger]

that'll stop it from running if the SpawnEnemyGroup methosd is called and uses deltaTime when it still has a value . . .

[acoustic sequoia]

so, that means how every many frames i'm paused i will expect the enemy spawner to spawn that many times...

[verbal dome]

You'd wantwhile , not if, right

[swift crag]

oh, I see how the bug is happening

yeah, I get it

      if (spawnInterval == 0f)
      {
        SpawnEnemyGroup();
      }

      spawnInterval += Time.deltaTime;
      spawnInterval = Mathf.Clamp(spawnInterval, 0f, rate * spawnrRateMultiplierActivated);

      if (spawnInterval >= rate * spawnrRateMultiplierActivated) spawnInterval = 0f;

You spawn a group if spawnInterval is zero

You set it to zero if the value gets too large

If you pause RIGHT as it gets past this limit, it'll have a spawnInterval of zero every frame

[acoustic sequoia]

exactly

[swift crag]

This is just a bug in your code. It's written wrongly.

You should do something more like this

[acoustic sequoia]

so a quick fix is to have a check right there to see if the game is paused

[swift crag]

delay -= Time.deltaTime;

while (delay <= 0) {
  delay += interval;
  DoThing();
}

interval is how long to go between spawns

delay is how long until the next spawn happens

using while makes sure it works right even if the interval is so fast that you get more than one spawn per frame

(and, obviously, you'll want to spawn enemies in that loop, too)

There is nothing conceptually wrong with a zero-duration frame. Any time-dependent processes shouldn't proceed at all during it

[swift crag]

(Also, the way you wrote this will cause slight errors over time -- notice how you just set spawnInterval to zero, no matter how far you overshot the target)

[acoustic sequoia]

im aware of this, this code of mine is old. i will subract it

[swift crag]

so, just rewrite it so that it spawns enemies in response to you going past the limit

instead of setting the counter to 0 and then reacting one frame later

[acoustic sequoia]

so for this, i'm not sure i understand its logic?

[swift crag]

suppose you want to spawn 1000 enemies per second

you are running the game at 10 frames per second

delay -= 0.1 -> suppose delay is now -0.007

interval is 0.001. we add interval to delay until it becomes a positive number again

spawning eight enemies in the process

(i added an extra line to the example to call a method)

[acoustic sequoia]

why do you want to do this part?

[swift crag]

to handle this situation

It is not strictly necessary, but it's more correct.

It's more relevant for things like fast-firing weapons

[acoustic sequoia]

wouldn't this not solve the issue, becasue what if the pause happens when the delay reaches the correct value? same issue happens again

[swift crag]

it's completely fine

notice how deltaTime isn't used anywhere inside the loop

we are simply adding interval to delay until the delay value becomes positive

Your code does something entirely different. It checks if spawnInterval is too big and sets it to zero if that happens

which means that it can get parked at zero forever if you pause at the exactly correct frame

Your spawn condition has nothing to do with checking if too much time has passed. It only checks if spawnInterval is zero.

It does become zero if you just passed the threshold...but it also becomes zero if the game is paused at the wrong moment

[acoustic sequoia]

ok so i think i get it now.. correct me if i'm still wrong lol

1. the game reaches the spawnenemygroup().
2. then enters a new while loop for the delay.
3. the interval is fixed and is used to reach the delay amount.
4. once delay is reached, execute SpawnEnemyGroup()

correct?

[swift crag]

No. Each time the loop runs, we spawn a group.

[obsidian plaza]

so basically my original solution wouldve worked

pause at the end of the frame

[swift crag]

No, that wouldn't have done anything

[obsidian plaza]

oh smh

[acoustic sequoia]

how do i pause at the end of fram?

[swift crag]

well, with Awaitable, you can ask to resume at the end of the frame

but that's non-relevant here

[acoustic sequoia]

ok

[swift crag]

the core problem would remain: spawnInterval is stuck at zero forever

[acoustic sequoia]

yeah

can't i just use a bool isPaused to prevent all of this?

[swift crag]

• Subtract Time.deltaTime from the delay every frame
• As long as the delay is <= 0:
  • Add the interval to the delay
  • Spawn enemies

That's it

[swift crag]

I mean, sure, but I'd rather just write code that doesn't break when the timescale is zero

There's a fundamental correctness problem with the existing code

[acoustic sequoia]

i'm sorry, i'm just not understanding how this works. the logical side of it.. i must be missing something, in my mind, what you are doing is just pushing back the inevitable sort of say... Time.deltatime is affected my timescale... so i don;t see how this helps during the paus

[swift crag]

Let's say the timescale is zero

Time.deltaTime is zero.

delay is currently 0.01

[acoustic sequoia]

yes

[swift crag]

Does anything happen?

[acoustic sequoia]

no becasue deltatime is 0

[swift crag]

Right. delay -= Time.deltaTime does nothing

and delay <= 0 is false, so the loop doesn't run

Now suppose delay is -0.01

What happens?

[acoustic sequoia]

i don;t want the condition to fail. that would complete the while loop

teh task would end

[swift crag]

The entire thing can sit in a while (true)

That is irrelevant

[swift crag]

This would be useless if it wasn't stuck inside something that looped. It'd run once and bail out.

[acoustic sequoia]

nothing agian to answer your question

[swift crag]

Incorrect.

while (delay <= 0) {
  delay += interval;
  SpawnThing();
}

This condition is now true.

We add interval to delay and call SpawnThing();

If interval is large enough, the loop terminates.

Otherwise, the loop runs again.

[acoustic sequoia]

i don't want to spawn thing lol

[swift crag]

It is a placeholder.

You can do whatever you want in there.

[acoustic sequoia]

i don;t want to do anything ! lol

[swift crag]

What?

[acoustic sequoia]

thats the whole point

[swift crag]

I don't think you're understanding anything I'm saying

[acoustic sequoia]

i must not be lol

[swift crag]

I am showing you how this approach correctly handles a timescale of zero

[acoustic sequoia]

when the game is paused. i want to do nothing and wait until unpaused

[swift crag]

notably, delay can't wind up being non-positive during a frame with a deltaTime of zero, because we subtract from it before we check it

your code subtracts from it one frame before it checks the value

[acoustic sequoia]

you have to write the code, becasue i'm getting mixed up withe the english and code intermixing. just take a small part of my function and write in your method of success so i can read the code

[swift crag]

This is it.

Replace interval with how frequently enemies should spawn per second

[acoustic sequoia]

hold on a sec. i'm going to give you a block. and edit it so it's correct..

[swift crag]

That's how the bug happened in the first place. It set spawnInterval to zero on the very last non-paused frame (but didn't do anything immediately).

One frame later, it started spamming enemies, because spawnInterval was parked at zero and never changed from that point

[verbal dome]

delay is like the bird in flappy bird, falling lower and lower
When you fall too low, you tap it until you are high enough

[swift crag]

The approach I suggested doesn't do that -- but even if you did write it in a way that can cause the enemies to spawn late, it won't malfunction (beyond being one frame off)

[acoustic sequoia]

    {
      elapsedTime += Time.deltaTime;
      elapsedTime = Mathf.Clamp(elapsedTime, 0f, rallyDuration);

      if (elapsedTime >= rallyDuration)
      {
        currentRally.Completed();
        EndRally();
        return;
      }

      if (spawnInterval == 0f) SpawnEnemyGroup();

      spawnInterval += Time.deltaTime;

      if (spawnInterval >= rate * spawnrRateMultiplierActivated) spawnInterval = 0f;

      await Task.Yield();
    }```
add what you are saying to this to make it work

i made the while(true) for you

[swift crag]

while (isRallyActive)
{
  elapsedTime += Time.deltaTime;
  elapsedTime = Mathf.Clamp(elapsedTime, 0f, rallyDuration);

  if (elapsedTime >= rallyDuration)
  {
    currentRally.Completed();
    EndRally();
    return;
  }

  float interval = rate * spawnrRateMultiplierActivated;
  delay -= Time.deltaTime;

  while (delay <= 0) {
    delay += interval;
    SpawnEnemyGroup();
  }

  await Task.Yield();
}

something along these lines.

note that I have renamed spawnInterval to delay (because that's what it represesnts now

the name was already misleading, though: it's not the spawning interval

spawnTimer could be more appropriate

[swift crag]

You may want a sanity check that interval is not zero

This kills the game

[acoustic sequoia]

so how do i reset the delay? or when?

[swift crag]

delay += interval;

this is inside of the while loop.

[acoustic sequoia]

ok so when the game is unpaused.. the delay is always greater than 0.. correct?

[swift crag]

At the end of the frame, delay will always be greater than zero

No matter what

If it isn't greater than zero, the while loop will add to it until it's greater than zero

This is a nice invariant. We know that, on the next frame, delay <= 0 must be false (before we subtract Time.deltaTime, at least)

On a paused frame, Time.deltaTime is zero

So we are also guaranteed that delay <= 0 will still be false

and thus nothing can possibly spawn on a pause frame

[acoustic sequoia]

ok wait .. hold on, i'm not understanding how delay is just floating around with no regulation... can delay get way too big?

[swift crag]

Why would it? We only add to it until it's greater than zero

then we stop

We are very carefully regulating the value of delay, to the contrary..

[obsidian plaza]

r yall still on this..

[acoustic sequoia]

omg my mind is just not comprehending this... shit

[obsidian plaza]

lol its just funny cause i thought it was a 2 line change

[acoustic sequoia]

lol to unscaled? lmao

[swift crag]

Do an example by hand, then. Pick an interval value (maybe 0.1) and a deltaTime value (maybe 0.03, or maybe 0.3)

See what happens.

[acoustic sequoia]

i trust you that it will work... i just don't use code that i don;t understand.. while i have you here (and i'm very appreciative of it) i'd love to understand it. (even though you have explained it probably well, it's just not clicking for me) sadly...

[swift crag]

That is why I suggested you work an example by hand.

Seeing how it behaves with:

• intervals much longer than the frame time
• intervals much shorter than the frame time

will illustrate why it's correct

[cosmic charm]

no longer can't move the object in the scene, why is that happening?

[swift crag]

Show your entire editor window in #💻┃unity-talk (this isn't a code problem)

[cosmic charm]

and no they are not static

[cosmic charm]

oh sorry

[acoustic sequoia]

i will take this into the areana with me and start writing it by hand, hopfully it will make sense after i do that. lol thank you

[teal viper]

What are you trying to move? You seem to have 2 objects selected

[cosmic charm]

the witch

[swift crag]

I wonder if having a deactivated object selected is at all relevant

[teal viper]

Or is that just hovered on

[swift crag]

oh, that's just hovered

[acoustic sequoia]

before i go, does it matter what i set the delay to? or is that just prefference

[teal viper]

How are you moving it?

[swift crag]

Start at interval if you want the spawner to wait for one cycle before spawning an enemy

[cosmic charm]

from the transform component

[swift crag]

Start at zero if it should instantly spawn

[teal viper]

And do the values in the component change?

[cosmic charm]

yes

[teal viper]

Then it moves.

[acoustic sequoia]

oh wait... doesnt this code spawn the enemy (interval) amoutn of times ?

[teal viper]

Maybe a video would be more helpful to see what you mean

[cosmic charm]

I mean yeah

but it doest show this thing

[swift crag]

No. It spawns an enemy every interval seconds.

[cosmic charm]

what ever it called

[swift crag]

those are handles

[cosmic charm]

yes it doesn't show them

[swift crag]

oh, one thing

switch from "Center" to "Pivot" (the shortcut is Z)

I bet the handles are just way off the screen

sorry, awful crop

top left of the scene view

Center finds the center of all of the bounding boxes of the renderers and colliders on the object

which can be very far away from the actual pivot point

[cosmic charm]

oh shoot

yes

[swift crag]

Center mostly exists as a prank

It is useful at times...very specific times!

[cosmic charm]

thank you ....

omg you saved me

thank you so much

[verbal dome]

I've seen 3 instances of someone getting pranked by Center today

[cosmic charm]

I love you already

what ever this creature is, I'm a fan of it from now on

thank you so much

[swift crag]

i get pranked by it every few days

[prime goblet]

it's very tricky because whenever you create a new project, your UI layouts and most general preferences get reset

same with pivot/center

quite annoying imo

[verbal dome]

Pretty sure you can save layouts as presets and stuff

Yeah

[weak talon]

i have a room object with this script on it

[SerializeField] private Animator anim;
[SerializeField] private BoxCollider boxCol;

public bool doorLocked = false;

private void OnTriggerStay(Collider other)
{
    if (other.gameObject.CompareTag("Player") && doorLocked == false)
    {
        OpenDoorServerRpc();
    }
}
[ServerRpc(RequireOwnership = false)]
private void OpenDoorServerRpc()
{
    Debug.Log("ClientRPC received. Playing door animation...");
    if (anim != null)
    {
        anim.Play("Door Open");
    }
    else
    {
        Debug.LogError("Animator component is missing!");
    }
}

the boxCol component is the collider of the door which is a child object of the room
and i want to detect collision coming from the boxCol component and check if the collision touching the boxCol component is comparetag player and do something if it is
can someone please help how to do that

[heavy knoll]

Anyone know how to correctly play sound for hitting and then destroying an object? Im currently using the same script for different objects and they are each having their specific data set in the inspector for them. I also have a SoundManager empty game object with 2 AudioSources. Just cant figure out how to get one sound and the other into the inspector slots.

https://paste.ofcode.org/328kBv2ggt4vWfsTWtcPLb9

[teal viper]

You can do PlayOneShot on the audio source instead of assigning a clip to it. Check the API docs of the audio source.

[heavy knoll]

wouldn't that mean i have to use the same breaking and destroying sound for all the objects that have the script if i set it within the script?

[teal viper]

No. You can pass in whatever sound you want.

You can get the clip reference from the destroyed object for example.

destroySFX.Play(thisObjectSound)

Not play, but you get the point I hope

[heavy knoll]

what would thisObjectSound be?

so i'd get rid of the empty game object with the sources on it to play the sound?

[teal viper]

An Audi clip

[teal viper]

No, you can do it with it as well. I was just basing off the code that you shared.

soundManager.Play(sound)
And the sound manager would call the play one shot or something on the audio source.

[heavy knoll]

im confused though

how do i get the audio sources into the inspector?

cause when i try dragging them in it only puts the top audio source into the audio source reference i have

[teal viper]

Where are you dragging the audio sources from and to where(a prefab? An object in the scene?)

[heavy knoll]

im trying to drag the top audio source from this SoundManager to the top reference slot and the bottom audio source to the bottom reference slot.

but it only lets me use the top audio source from the SoundManager object in the reference when i drag it in

I want it to play the footstepsfx on getting damaged and dashsfx on getting destroyed

but i dont wanna just hardcode those sounds into the script because i wanna make another object eventually that will have a different sound when getting hit and destroyed so i can just change it in the inspector

[teal viper]

If you have a setup like this, it might be wiser to only reference the sound manager object in your destructible object and just call the appropriate methods on it. Referencing the audio sources directly beats the purpose of a sound manager.

[heavy knoll]

ooh ok, ya i just tried it like this cause i saw a post online with someone talking about good ways to do it and that was one of them

is there a better setup i should be using to play the different audio sounds for each object?

[heavy knoll]

if i do it like that though wouldnt i still need to have something referenced in the inspector though so the sounds can be different per object?

[teal viper]

Yes, you'll need to reference the audio clips of the different sounds you want to play. That's it.

[teal viper]

Then you probably misunderstood them. Because what you're doing now is the most(or almost) inefficient way.

[heavy knoll]

if im just referencing audioclips instead of audiosources how would i modify the pitch and volume settings for each individual object?

[teal viper]

You can have this data defined on the destroyable object as well and pass it all together to the sound manager that would actual deal with it.

Ideally, you'd use scriptable objects here so that the sound data is encapsulated in a separate object and doesn't clutter the destroyable object inspector.

[heavy knoll]

i was trying a bit to figure out how to use scriptable objects, but i couldn't really find/figure anything out that could help with using it in the use case of a resource gathering system

[junior ivy]

Let's say that I have empty GameObjectAbc and a MonoBehaviour ScriptAbc.cs for it.
Can I add GameObejcts and Componenets from that script to compose a tree where GameObjectAbc is a root?
If yes then how is this possible to add a GameObject as a child to the ScriptAbc component? I've read that components can't have GameObjects as parents.
In other words: I want to create a scene tree purely from the code

[heavy knoll]

i tried watching a few vids too talking about the basics of it, but none of what they were showing seemed to be close to what I'm trying to use scriptable objects for

It was all just like making a basic scriptableobject asset from the asset menu and then setting simple values in that but not actually using them for anything in the game

basically i dont rlly understand how to convert my current script with all the methods and variables within into a scriptable object system

[eager spindle]

the way I do it is

Item.cs - describes an item. does not change at runtime

public class Item : ScriptableObject {
  string name;
  //Add anything you need here
}

Inventory.cs, assigned to each player

Dictionary<Item, int> items; //contains number of items

but if you need to store the state of an item there's other ways to do it

seems to align with what you're doing

[teal viper]

You use scriptable objects to define many different data sets. Then you use the one so that had the desired data set. You can pass it around for example, instead of passing tens of separate variables.

[heavy knoll]

im more trying to do like rocks and trees and ores that spawn around my map that i can mine and all have different stats without having to make a new script and prefab for each type

[eager spindle]

Those aren't inventory items, you can simply make a HarvestableResource script. When the object is hit, make it drop an item

You only need one HarvestableResource, no need to derive it. Then set the dropped item to the item of your choice like rock or wood

[heavy knoll]

if i use scriptable objects and i cant change them at runtime would that make it not possible to have like a weapon scriptable object that has an int for damage and have that value be like 10 and then be able to change that damage value of the item to like 20 if something happens in game

[eager spindle]

just curious why do you want to use a scriptable object for this? do you intend to create 1 scriptable object per tree/rock?

[heavy knoll]

uh idk, im still pretty new, that's just what i got recommended to use

[teal viper]

It depends on the context. At the moment I recommend to use scriptable objects for sound data, as apparently they want different sounds with different pitches and what not for different object types.

Then you could just pass the SO reference to your sound manager and it would play the desired sound with your settings.

[eager spindle]

Think of the workflow of prefab vs scriptable object

If you use a prefab, you can simply Instantiate destructible trees and rocks
For scriptable objects, you'll have to make a copy of the scriptable object, and represent that ScriptableObject in the world(through a tree/rock object)

I'm not saying avoid SOs entirely but think about why you need them

[heavy knoll]

This is what i currently have right now, one script called ResourceNode on each object that i want to be its own thing like iron ore or gold ore and they have their own values set in the inspector for the script. And another script called Playerhit which is just like a temporary script i have to test the functions before i add my tool system. https://paste.ofcode.org/38wJnL6n2yU3rLnUvVFXHgh https://paste.ofcode.org/32h48wervqkLFVCtcswFgwF

[teal viper]

That doesn't make sense. Components don't know anything about the hierarchy. They're just attached to a GameObject. gameObjects take care of hierarchy and contain one or many components. That's the only relationship there is.

[junior ivy]

thanks, that's what I wanted to hear, now I'm sure

I'm learning with chatgpt and it tried to add GameObject as a child to the component and I freaked out

[rich adder]

gpt is trash not a good way to learn

[eager spindle]

chatgpt has never coded a game before in unity don't let it tell you what to do

everything it spits out is garbled hearsay

[junior ivy]

it's good, I was able to do advanced things in godot much faster in compare to manual research

[eager spindle]

it's even worse for godot

[junior ivy]

it was even worse in godot but I was able to recreate his intentions

[rich adder]

if its good why are you here lol

[junior ivy]

it's not perfect

[eager spindle]

because 3.x and 4.x API changed a lot, using Godot for 4.x can give very wrong answers

[junior ivy]

I would spam you out with questions if not AI

[rich adder]

we rather get questions to clairfy something than you going to GPT and learning worse

[junior ivy]

oh no, I'm not learning from it... I'm gathering info and learning from that

[rich adder]

not even about being perfect, is just bad. period.
you wont learn anything, and whatever you learn is probably flimsy at best

[junior ivy]

LMAO if I trusted this AI I wouldn't achieve anything
